iPower Flexible 4 Inch 25 Feet Aluminum Ducting 4 Layer Protection Dryer Vent Hose for HVAC Heating Cooling Ventilation and Exhaust, 2 Clamps Included, Black

great quality and fits perfect. the black color looks great and it’s super thick and durable, yet super flexible. very easy to install

Just ducting but I had to go back on and review this item because I've been using it for my laser cutter smoke ventilation system now for over a year and it has kept it's shape, not cracked, not buckled weird or quit working in any way. So I gotta say it's pretty great and works well.

I recently purchased the iPower Flexible 4 Inch Aluminum Ducting for my HVAC system, and it has worked well for my needs. The 8-foot length is perfect for my setup, and the 4-layer protection provides excellent durability, ensuring it can handle high temperatures without any issues. The included clamps make installation straightforward and secure.One of the standout features is its ability to handle various applications, from dryer vents to exhaust fans, which adds to its versatility. I also appreciate the black finish; it blends nicely with my home’s decor.

Good replacement - hard to install with vinyl outer cover and foil inner lining

Works as intended for resin 3d printer exhaust fan

Some customer reviews made me hesitant given the measured diameter of the product. My bathroom fan and wye adapter are about 2 15/16". It is a snug fit, but without too much fuss I was able to fit the hose. This product should work with any item that has an outside diameter of exactly 3" or less.As far as I can tell, this product is identical to most 3" aluminum ducting at time of review (probably re-branded), so quality should similar to other products. This product in particular was the best value. I like that it included two hoses, and thus 2 sets of clamps.

Great product, easy installation, looks durable, fits on my exhaust fan. Great value.

Good stuff, it's tough enough to abuse with a heavy coil, good layers, no leaks (believe it or not a lot of cheap ducts leak quite a bit). I'm using it for smoke evacuation on a CNC laser, so it's getting beat up and dragged around and enduring workshop conditions and it's perfect for this but half the cost of comparable duct the home store had, plus it's got the nice black cosmetic layer. Also, dimensions are spot on, good fit. The included clamps are not bad at all. I imagine it's hard to stand out when making precut lengths of ducting but they went the extra mile adding tape to prevent delamination in transit, bending over the sharp wire, etc. and I appreciate it.
